Solve for the x in the following prpportion x/60 = 9/5

  • college math -

    Cross multiply:

    x/60 = 9/5

    5x = 540

    Solve for x.

  • college math -

    If both terms are equal, that is:
    x / 60 = 9 / 5

    Then, x is to 9, as 60 is to 5.

    60 = 5 * 12

    so, x = 9 * 12

    thus, x = 108.
